[Structure] An EVA insole 2 is used as a substrate at a lowermost portion, a shock absorbing material polon 3 is bonded to a forefoot portion, and a latex heel pad 4 with an arch support is bonded to a heel portion. Further, a neoprene rubber fabric 1 obtained by laminating a jersey material is adhered to the upper surface and the buffed side surface from above.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 Insole for general use of shoes for shock absorption and molding of lasts

[0002]

[Prior art]

 Conventionally, this type of insole uses (a) a hard material or a heavy material, but (b) uses only a shock-absorbing effect, and (c) forms a footprint using a heating device such as a dryer. Things are known.

[0003]

[Problems to be solved by the invention]

 In the former (a) and (b), although the former (a) and (b) have shock absorption properties, they are hard and heavy, so they are easy to get tired, and a surface material with a large friction coefficient generates frictional heat and can be used for a long time. There was a problem that beans were easily formed on the soles.

[0004] In the latter case (c), the insole cannot be formed without using a heating device such as a drier or equipment, and the material once formed by heat is hardened due to the property of being hardened. Inability to cope with the changing shape of the soles, not always obtaining a feeling of fit, fatigue and stress due to prolonged use, and the metatarsal head, plantar muscles, Had a cause of pain.

[0005] The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to omit molding equipment and work, and to naturally form a last while wearing it. It is intended to provide an insole that has excellent shock absorption, prevents fatigue and pain, and uses a surface material with a small coefficient of friction to suppress frictional heat and prevent the leg of the sole.

[0006]

Means for Solving the Problems To achieve the above object, the insole according to the present invention can be made soft, lightweight, and shock absorbing by using an EVA material as a substrate.

[0007] The use of neoprene rubber as the surface material makes it lightweight and soft, and the pressure of the weight is applied, so that the last can be formed naturally.

[0008] In addition, neoprene also has a heat retaining property due to a foaming material.

Further, by using a composite material of neoprene rubber obtained by laminating a jersey material, the coefficient of friction of the jersey portion is reduced, and the generation of beans on the sole due to frictional heat is prevented.

[0010] In addition, by using a heel pad with an arch support having excellent cushioning properties from the heel portion to the arch portion, an impact received from the ground when walking, running, or jumping at the heel portion. It absorbs water and protects the foot, and at the same time, has excellent cushioning properties, which helps to increase jumping power and propulsion.

[0011] Furthermore, since the arch portion is supported, the fit between the insole and the sole increases, and even if the arch falls due to prolonged walking, running, jumping, or standing, the shape of the sole changes. It can respond flexibly and can prevent fatigue and pain stress due to slippage.

[0012] Furthermore, it is possible to reduce the burden on the head of the metatarsal bone centering on the toe ball by bonding the shock absorbing material to the forefoot.

[0013]

【Example】

 Embodiments will be described with reference to the drawings. The insole 2 made of EVA shown in FIG. 4 is used as a substrate at the lowermost part, and a polon 3 of a shock absorbing material is adhered to the forefoot part, and a heel pad with a latex material arch support is attached to the heel part. 4 is adhered. Further, a laminating insole is formed by adhering the upper surface and the buffed side surface so as to be wrapped with the neoprene rubber cloth 1 in which the jersey material is laminated.

Regarding the variation of the heel pad, not the latex material, but a flat EP material is cut into the shape of the heel pad, and the pedestal pad 6 is attached to the arch portion to produce the heel pad 5 having the arch support. .

[0015]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. However, the effects on claim 1 will be described in the following six items from a to a.

[0016] (a) The use of lightweight materials for all parts has reduced the burden on the feet, thus preventing fatigue.

[0017] A, since the surface material is made of neoprene rubber, which is made by laminating a jersey material, it is possible to form a last naturally simply by wearing the jersey material. As a result, the generation of beans on the sole due to frictional heat was prevented.

C. By using a soft and durable heel pad made of latex material or EP material, it absorbs the impact on the heel, prevents heel and knee pain, and supports the arch. The arch support can be prevented from fatigue due to the fall of the arch, and the arch support is not harder than the conventional insole, and the arch is flexibly supported, so the fit between the insole and the sole increases, and long-time walking, running, jumping The arch support can be flexibly supported even if the shape of the sole changes due to the fall of the arch in the standing position, and fatigue and pain stress due to slippage can be prevented. It was comfortable without hurt.

D. Regarding the shape of the insole, by raising the heel, the body leans forward, and at the same time, supports the arch, and the toes develop to prevent and improve the formation of the arch and hallux valgus. Helped improve toe performance and helped prevent athlete's foot.

(E) In addition, since the shock absorbing material Polon is used in the forefoot, the impact on the entire metatarsal head centering on the ball of the foot can be reduced.

Mosquitoes, which are all made of foaming materials, have excellent heat retention and prevent the feet from getting cold.

The upper surface and the (buffed) side surface of the insole are bonded with the neoprene rubber fabric obtained by laminating the jersey material according to claim 2, thereby increasing the adhesive strength and comparing with the case where the jersey material is not wrapped. In addition, the durability against moisture increased and the film became hard to peel off.

By using the heel pad of EP material in which the pad portion is adhered to the arch portion instead of the latex material, the durability is higher than that of the latex material, and the market (impact, It is easier to use in severe markets where pressure and friction are severe.
